I think the majority agrees....MK is THE park.
It is full of magic,and it captures the pure essence of Disney. That castle just brings back so many childhood memories of watching Wonderful World of Disney on TV.
It has aged well, it's timeless, and there's something to interest every one young and old.
I love all of WDW, but MK will always be my favorite because it is the first park I visited on my very first trip in 2002. And every time I return it's the first park I go to when my vacation begins....
